If you haven't retained the data for each of the application types, it would be best to go with a single badge. I prefer badges for each app, but it really irks people off when their past contributions aren't reflected. Just an idea to throw out there.

OK four years since Badges were first talked about so I guess the Project has decided that there will be no Badges ???

It is a shame as it is another way to get people interested in the science you are doing as it adds another competitive measure.

Hope you re consider soon.

Sorry, but I have to disagree with you there. The badges have little or nothing to do with getting anyone interested in any science of any kind.

The badges are there for the glory seekers, at least for the most part. Do I want my computer cycles to be recognized? Sure I do, most people probably do. And the points do that just fine.

We all put in a few minutes for each project and then don't turn the computer off, at least if we either really want to help whatever project or seek points.

Takes some thinking for sure. I used to be a programmer and it took me a while to learn what I know and there are still things I don't know.

Some people, either lucky or addicted, don't know which, spend quite a bit of money building dedicated computers for BOINC. Wish I was in the lucky group and had the money to do that.

You are correct, at least in part when you say the badges add a competitive measure. But the points do that also. So the badges are just extra work for the admins.

I'm sure the admins have enough work to do already with their regular paying jobs, normal lives, and then their normal duties here. Then they have so many people asking the same questions so often. For example, "Are we getting badges", "Why no tasks", and others. They've already answered those questions, and more, a lot of the time in the same thread a couple of posts before another person asks again. If the question hasn't been answered in the thread it is asked again in, it's likely it has been answered somewhere on the message boards and a search would find it. But I reckon it's to hard to do that because the same questions keep getting asked over and over.

I don't read the message boards that often on any project I'm part of. But when I do, I see this on all of them.
